1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 90405361, compound

Participants

Reaction Steps

23 mg of 2-(4-(sulfamoylmethyl)phenyl)acetic acid (0.1 mmol), 20 mg of 4-(piperazin-1-yl)-6-(2,2,2-trifluoroethyl)thieno[2,3-d]pyrimidine (0.067 mmol), 20 mg of EDCI (0.1 mmol) and 4 mg of DMAP (0.033 mmol) was stirred in 2 mL of DCM. After 2 hs reaction mixture was concentrated and residue was loaded on silica gel column. Elution with DCM-MeOH 9:1 and evaporation of fraction produced 38 mg of (4-(2-oxo-2-(4-(6-(2,2,2-trifluoroethyl)thieno[2,3-d]pyrimidin-4-yl)piperazin-1-yl)ethyl)phenyl)methanesulfonamide (compound 44). 1H NMR (400 MHz, CDCl3): δ 8.44 (s, 1H), 7.36 (d, 2H, J=8 Hz), 7.25 (d, 2H, J=8 Hz), 7.20 (s, 1H), 4.88 (s, 2H), 4.26 (s, 1H), 3.5-4.0 (m, 10H). ESI MS [MH+]: 514.1. Its monohydrochloride salt was obtained by adding 1 equivalent of 1N HCl solution in diethyl ether to a solution of compound in ethanol.
